She was completely asymptomatic and had no symptoms of voiding difficulty prior to this. On physical examination, she was found to have a firm tender mass measuring 2.5x2 cm, involving the posterior periurethral region. The urethral orifice could not be separately identified.

There was no significant postvoid residue. MRI was performed for further characterisation of the lesion and its relation to adjacent structures.
